Diffuse malignant peritoneal mesothelioma is mesothelioma cancer in the lining that surrounds the abdomen (stomach). Diffuse means that is the cancer is spread out.

Peritoneal or Peritoneum is a smooth membrane, which lines the cavity of the abdomen (stomach). It helps to protect the contents of the abdomen. It also produces a lubricating fluid. This helps the organs to move smoothly inside the abdomen as we move around.

Peritoneal mesothelioma accounts for approximately 10% of mesothelioma cases.

Symptoms of Peritoneal Mesothelioma

When the symptoms of peritoneal mesothelioma appear, they typically include abdominal pains,abdominal weakness, weight loss, loss of appetite, nausea, and abdominal swelling.

Fluid often accumulates in the peritoneal space, a condition known as ascites. Over time the wasting symptoms can become more and more severe.

The growing peritoneal mesothelioma tumor can exert increasing pressure on the organs in the abdomen, leading to bowel obstruction and distention. If the peritoneal mesothelioma tumor presses upward, it can impair breathing capacity.

If the peritoneal mesothelioma tumor pushes against areas with many nerve fibers, and the bowel distends, the amount of pain can increase.
